JOHN F. OCONNOR, OF CHICAGO, ILLINOIS, ASSIGNOR TO WILLIAM I-I. MINER, OF CHICAGO, ILLINOIS.

CAR-DOOR-SEALING DEVICE.

Application filed October 11, 1911.

To all whom it may concern Be it known that I, JOHN F. OOoNNoR, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Car Door Sealing Devices, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to improvements in car door sealing devices.

The object of my invention is to provide a car door sealing device of simple construction, efficient operation, and easy and cheap manufacture.

In the accompanying drawings forming a part of this specification Figure 1 is a front elevation of a pair of doors for refrigerator or other railroad cars showing my car door seal in position. Fig. 2 is a front elevation of my sealing device with parts in posit-ion, as when the car is sealed. Fig. 3 is a side elevation of my sealing device showing the position of parts when the car is sealed. Fig. 4 is a vertical section of my sealing device showing the pin in its raised position. Fig. 5 is a vertical section on line 5-5 of Fig. 2 showing the position of parts when the tablet is in position and the car sealed. Fig. 6 is a vertical section on line 55 of Fig. 2 showing the position of parts when the tablet is being broken by the raising of the pin.

In the drawings 7 represents the left hand, and 8 the right hand door of the ordinary refrigerator car. 10 a usual construction of door locking mechanism,though it will be readily apparent that any usual form of similar mechanism may be used, 11 the handle of the same, 12 my car door seal.

My car door seal lock 12 is preferably of malleable iron, and comprises a member or casing 13, preferably vertically extending and secured by means, preferably bolts or rivets 14, to the car door 7. The said casing 13 is preferably hollow in its upper portion 15, the said upper portion being provided near its forward side at its upper edge with a preferably vertical perforation or opening 16, and with a similar perforation 17 near the lower forward portion of the said upper portion 15 of the casing 13. A staple 18, preferably integral with the lower portion of said casing 13, extends outwardly from Specification of Letters Patent.

Serial No. 653,989.

the lower portion of the said casing 13, the said staple being provided with a preferably vertical perforation 19 in vertical line with the said openings 16 and 17. The upper portion 15 of the said casing 13 at its forward face is provided with a preferably rectangular opening 20, the lower edge of which is provided with a shoulder 21. One of the sides 22 of said upper portion 15 of the casing 13 is provided with a vertical slot 23.

24 is a pin provided at its upper end with a head 25, and at its lower end is preferably provided with a transverse slot 26. The said pin 24 is also provided on its upper forward face with a preferably integral shoulder 27, and at one of its side faces 28 near the lower end of said pin with a sub-- stantially L shaped shoulder 29, and on the same side of the said pin near the middle portion of its vertical length with a prefer' ably integral lug 30, preferably of substantially parallelogram shape in plan View.

31 is a pawl placed within the hollow portion of the casing 13, and sustained therein by means, preferably a transverse bar 32 passed through the upper portion 33 of said pawl 31, and preferably riveted to the casing 13. The said pawl 31 is provided at its lower forward portion with a boss 34.

The pin 24 passes through the openings 16, 17 and 19 in the casing 13, and the pawl 31 is sustained in the said hollow portion of the casing 13 back of the said pin 24 in a position to permit the engagement of the boss on the upward movement of the pin 24 with the upper surface 36 and the forward surface 37 of the lug 30, and cause the said pawl 31 to move in a forwardly direction into the opening 20 of the case 13, and after the said lug 30 has moved upwardly by the boss 34 of the pawl 31 the said boss 34 engages the rear face 38 of the shoulder 29 of the pin 24 until the boss 34 comes into contact with the face 39 of the shoulder 29, and thus prevents further upward movement of the pin 24.

The member 11 of the door locking device is preferably hasp like in construction, though it is readily apparent that any similar device or any ordinary hasp may be used, and is provided with an opening 40 through which, when the doors 7 and 8 are in a closed position, the staple 18 of the casing 13 passes, thus permitting the pin 24 to be inserted from above through the openings 16, 17 and 19 in front of the member 11, and by means of which pin the hasp like member 11 is held in its locked position.

The slot 23 in the casing 13 is of a size suflicient to permit the insertion edgewise, when the pin 19 is in its raised position, of a tablet 41, preferably of clay or other similar material, which may bear letters, figures or characters giving information relative to the car upon which my device may be placed, its destination or contents. The said tablet 41 is dropped to its position in which the lower portion of the same rests back of the shoulder 21 of the casing 13, and the upper portion of the same upon dropping the pin 24- to its closed position, as shown in Fig. 5, is in close proximity to the shoulder 27 of the pin 24. The said tablet 41 is preferably of a size slightly larger than the opening 20, and suflicient to close the same. When the said pin 24 is in its closed position, as illustrated in Figs. 2, 3 and 5, a seal strip 42, or any similar device may, if desired, be inserted through the slot at of the pin 24, or a padlock or any similar locking means may be used.

From the foregoing description the utility and operation of my sealing device will be apparent. hen the same is applied to a railroad car door the pin 24 is lifted to its open position, as shown in Fig. 4. The tablet 41 is inserted through the slot 23, and the pin dropped to its closed position back of the opening 18 of the casing, and permitting the same, and the letters, figures or characters which may be used thereon to be readily seen. During the dropping of said pin 24 the boss 34 of the pawl 31 contacts with and passes rearwardly along the lower face of the lug 30, until on passing said lug the pawl is in its normal position, as shown in Fig. 5. Now the shoulder 27 of the pin 24 closes the slot 23, and the hasp like member 11 being back of the said pin in its locked position it is clear that to open a car door thus sealed the pin 24 must be raised to its unlocked position, as shown in Fig. 4, and that the same cannot be done without breaking the tablet 41, as illustrated in Fig. 6. In raising the pin 24 the boss 34 of the pawl 31 engages the upper face 36 of the lug 30, and passes along the same, forcing the pawl 31 against and into the said tablet 41 and breaking it. Then having passed the said lug 30 the pawl 31 of its own weight falls back and to the rear of the shoulder 29 of the pin 24, and contacting with the face 39 of the shoulder 29 prevents the withdrawal of the pin from the casing.

It will be clear that trainmen or others may by inspection of the tablets determine readily whether or not the doors of a car, or other doors to which my device may be applied, have been opened, by observing, as easily and quickly may be observed, whether or not the tablet is broken. Thus thefts of goods from railroad cars may be readily detected, and by frequent inspection of the tablets the points in the travel of a railroad car between which an opening of the same occurred may be easily learned.

I realize that considerable variation is possible in the construction herein described without departing from the spirit of my invention, and therefore by the foregoing accurate description I do not intend to be limited thereto, except as pointed out in the following claims.

I claim:

1. A door seal comprising a perforated casing consisting of a hollow portion and a flange, a slot in said hollow portion through which a frangible tablet may be inserted, a pin operating through the perforations provided with a shoulderon its forward face adapted to close said slot when the pin is projected, a pawl hung within the hollow portion of said casing, said pawl having a boss and the said pin being provided with a. lug adapted to engage with the said boss on longitudinal movement of the pin.

2. A door seal comprising a perforated hollow casing, an aperture in said casing for displaying a frangible seal, and a slot in said casing for the insertion of said seal within the casing, a slidable pin operating through said casing provided with a shoulder adapted to close said slot when the pin is projected, a pawl hung within said casing, and a lug on the said pin adapted to move the pawl toward the seal when the pin is retracted and away from the seal when the pin is projected, and a further shoulder on said pin to engage the pawl when the pin is retracted and prevent the removal of the pin from the casing.
